我想更改枢轴列的顺序。我该如何更改？
pivot_table方法中是否有任何参数？
从此更改：
| category | B | C | A |
|categoryA |
| adult |
| child |
|categoryB |
| adult |
| child |
|categoryC |
| adult |
| child |
对此：
| category | A | B | C |
|categoryA |
| adult |
| child |
|categoryB |
| adult |
| child |
|categoryC |
| adult |
| child |
